Doc Type: Bug Fix
Doc Text:
A flaw was found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality.

Description Martin Prpič 2015-07-03 09:59:29 UTC
Linux kernel built with the networking support(CONFIG_NET) is vulnerable to an infinite loop issue. It could occur while receiving(recvmsg(2), recvfrom(2)) data over UDP channel, with an incorrect checksum value.

An unprivileged user could use this flaw to cause DoS(CVE-2015-5364) to a remote system via specially crafted UDP packets.

The CVE-2015-5366 issue is also a DoS, but is limited only to the affected application and not the entire system.
